Movies via SMB

First of all, I´m not an English native speaker, so please excuse my mistakes.
I´ve successfully mounted my shared forlder by SMB and I can play files in streaming but only these ones under 500 Mb. For movies with more than 500 Mb it keeps like waiting but nothing happens. If I push to play it again a message shows up saying that there were too many mistakes and is aborted. Any solution? I hope you understood my question.
Adios

You can try adjusting the cache settings in nitoTV > Settings. This should improve playback.
